Kobanite (Jiangsu) New Materials Co., Ltd. is a materials technology company specializing in the conversion of spent refractories into engineered secondary refractory raw materials.

We transform carefully selected and controlled sources of spent refractories into refractory raw materials with stable chemistry, controlled particle size, consistent batch quality and full traceability through professional sorting, crushing, magnetic separation, screening, fine grinding, homogenization and laboratory characterization.

Our product portfolio includes secondary tabular alumina, secondary chrome-corundum, secondary alumina-carbon, secondary magnesia-carbon, secondary DBM, secondary high-alumina refractory materials, secondary AZS and high-purity alumina, serving refractory manufacturers and high-temperature industries including refractories, steel, glass, cement and other industrial applications.

Kobanite's core strength goes beyond material recovery. It lies in our capabilities in material engineering, formulation-oriented development and refractory application.

With technical input from Wuhan University of Science and Technology and leading global refractory companies, combined with extensive experience in the refractory industry, we understand the complete journey of a raw material — from its source and processing to chemical composition, particle-size distribution, formulation and final application.

Supported by advanced analytical capabilities including Bruker WDXRF and laser particle-size analysis, together with large-batch homogenization and rigorous batch management, we continuously control key chemical components, impurity levels, particle-size distribution and batch-to-batch consistency.

We do not simply process spent refractories. We redefine the material value.

From material recovery to material engineering, and from supplying individual raw materials to application-oriented development, Kobanite is committed to provide refractory manufacturers with reliable, consistent and sustainable secondary refractory raw material solutions.
